      abstract     = {Taste research has been hampered by technical difficulties,
                      mostly because liquid taste stimuli are difficult to control
                      in terms of timing and application area. Exact stimulus
                      control requires a gustometer, but the existing devices are
                      either not well-documented or rather inflexible. We designed
                      a gustometer based on a computer-controlled, modular pump
                      system, which can be extended via additional hardware
                      modules—for example, for heating of the stimuli or sending
                      and receiving triggers. All components are available for
                      purchase “off the shelf.” The pumps deliver liquids
                      through plastic tubing and can be connected to commercially
                      available or custom-made mouthpieces. We determined the
                      temporal precision of the device. Onset delays showed
                      minuscule variation within pumps (SD < 3 ms) and small
                      differences between pumps (< 4.5 ms). The rise time was less
                      than 2 ms (SD < 2 ms), and the dosage volume bias was only
                      $2\%.$ To test whether hemitongues could be stimulated
                      independently, we conducted a behavioral experiment. A total
                      of 18 participants received tasteless stimuli to the left,
                      right, or both sides of the tongue. The side of stimulation
                      was correctly identified on $91\%$ of trials, indicating
                      that the setup is suitable for lateralized stimulation.
                      Electroencephalographic responses to water and salty stimuli
                      were recorded from two participants; the stimulation
                      successfully evoked event-related responses, demonstrating
                      the suitability of the device for use in
                      electrophysiological investigations. We provide a
                      Python-based open-source software package and a Web
                      interface to easily operate the system. We thereby hope to
                      facilitate access to state-of-the-art taste research methods
                      and to increase reproducibility across laboratories.},
